Specification of Letters Patent.

Patented Jan. 15, 1907.

Application led February 28, 1905. Renewed .Tune 25, 1906. Serial No.323,347.

DER, a citizen of the United States, residing at Washington, in theDistrict of Columbia, have invented new and useful Improvements inMarine Electric Wharfage, of whichthe following is a specification.

This invention has relation to marine elec tric wharfage; and itconsists in the novel construction and arrangement of its parts, ashereinafter shown and described.

The object of the invention is to provide a Wharfage of a fixed naturewhich is simple and cheap of construction and operation and which isadapted to be located at places along the coast and upon river-shoreswhere the goods to be delivered and received from ships is not ofsufficient quantity to justify the establishment and maintenance ofwharves of the usual character and con struction.

The wharfconsists,primarily,ofanelevated cable or track which extendsfrom the shore out over the water and at its outer end is extended at anangle to the general outward line of direction of the main portion ofthe said track. Under the said angular extension of the track is erecteda platform upon which goods are delivered from vessels and upon whichgoods are laced to be delivered to vessels. A series o electric-currentwires follow the track in its outward direction, and at the point wherethe said wires approach the said platform they are connected toinsulated guides, which extend over the platforml A carrier is adaptedto travel upon the said track and is provided with a motor andtrolley-arms which engage the said current-wires and the guides locatedat the ends thereof. A means for generating and supplying current islocated upon the shore.

Said means consists, preferably, of a rotary gas or gasolene engine, tothe shaft of which is attached the shaft of a rotary electric generator.Storage batteries are also provided,

and the electric generator is connected with` a switchboard, which inturn is connected with the storage batteries and the currentwires insuch manner that by throwing appropriate members of the switch thecurrent may be generated or stored in the battery, or it may begenerated and sent along the current-Wires, or the stored current may besent from the battery along the current-wires. The fixtures supportingthe trackway may be provided with electric-light xtures which areelectrically connected together and also connected with the generator orbatterythrough the switchboard and connections above described, so thatthe wharf may be properly illuminated at night.

In the accompanying drawings, Figure 1 is a landscape view showing thegeneral outline of the system and appliances connected therewith. Fig. 2is a top plan view of the outer end of the wharf system, showing thediagram of a vessel in proper position with relation thereto forunloading. Fig. 3 is a side elevation of the parts of the systemillustrated in Fig. 2. Fig. 4 is a diagrammatic view showing thecurrent-Wires and mechanism for controlling the same.

The system consists ofthe suspended cable or'track 1, over which arelocated the wires 2 2 and 3 3. All of the said wires are parallel toeach other and parallel to the track. The wires 2 2 and 3 3 and cable 1are supported by the uprights 4, which are xed in thel earth` or alongthe bottom of the watercourse. The wires 2 2 and 3 3 extend along thecable 1 substantially along its entire outward length. At its extremeouter end the said cable 1 extends at an angle to the general outwarddirection of the cable, and below said angular extension is located aplatform 5. The guides 6 6 follow the angular extension of the track 1and are connected to the outer ends of the current-wires 2 2 and 3 3.(See Fig. 2.) Just outside of the outer edge of the platform 5 the piles8 8 are driven, and to said piles a vessel 9 may be lashed for loadingor unloading upon the platform 5. A carrier 10 is provided with asuitable motor and is adapted to travel upon the track 1.

Said carrier is provided with the trolley-arms 11 the upper ends ofWhich engage the current-wires 2 2 and 3 3 and, when over the platform5, the guides 6 A station is located on shore which is provided withsuitable means for generating the electric current. Said means consists,preferably, of a rotary gas or oil engine 12, which is fed by oil from atank 13. The rotary generator 14 is located opposite the gas-engine 12,the shaft of the said rotary engine being in alinement with the shaftofthe gas-engine IOO 12. A series of storage batteries is also provided,and a switchboard 16 is suitably located and provided with suitableswitches. The Wires 17 17 connect the generator 14 with the switch 16'.The wires 18 connect the storage battery 15 with the switchboard 16, andthe wires 19 connect the switchboard 16 with the current-wires 2 2 and 33. The wire 20 connects the electric-light fixtures 21, suitably locatedalong the supporting fixtures of the system.

Description and arrangement of the currentwires, as illustrated in Fig.4, is as follows: As shown in the said figure, a represents leither thegenerator 14 or the storage battery 15. The Wire 22 connects one pole ofthe generator or storage with the switch-socket 23. A wire 24 connectsthe opposite pole of the source of supply a with the switch-socket 25.The fuses 26 26 are located at suitable points on the wires '22 and 24.The switch 27 is adapted to enter the sockets 23 and 25, and the wire 28connects one of thek ends vof said switch with the socket 29, and theWire 30 connects the other end of the switch 27 with the socket 31. Wire28 with one of the line-wires 2.

The wire 32 connects the The wire 33 connects the wire 30 with theother' line-wire 2. The line-wires 2 2 are connected through thetrolley-arms of the carrier with the field 34 of the motor 35. Thecross-wire 36 connects the socket 29 with the socket 37, i

and the 4cross-wire 38 connects the socket'31 with the socket 39. Thepole-changer 40 (shown in the form of a switch) is adapted to be swunginto the sockets 29 and 31 or 39 kand 37. One end of the -switchconstituting the pole-changer 40 is connected, by means of the wire41,(with one of the line-wires 3, and the oppositeend of the said switch40 is connected, by means of the wire 42, with the other line-wire 3.The rheostat 43 is located, pref- 27, along the wire 28, along the wire32 to the inner current-wire 2', thence through the field-magnet winding34, along the outer curl rent-wire 2, thence along wire 33 to wire 30,

then through switch 27, along wire 24back to the opposite pole of thegenerator a. At the same time the current passes from the wire 30,through the socket 29, and along wire 36 to the socket 37, thence alongone end of the switch 40 to wire 42, thence along the said wire 42,through rheostat 43 to the inner current-Wire 3, thence to the armature35, thence along the outer current-wire'3, thence along wire 42 to theother end of the switch 40, thence to socket 39, thence along thecross-wire 38 to socket 31, thence back to the generator over the wire30 and its connections. By supplying the current to the armature andeld, as above described,

When the carrier goes out to the platform,

its trolley-arms pass from the current-wires 2 2 and 3 3 onto theinsulated section 6 6, which cuts off the current and the carrier stops.In the meantime the carrier has traveled along the angular extendingportion of the track 1 and runs out so that the operator on shore cansee it. He therefore reverses 'the switch 40, and when the carrier isloaded it is run back, so that the trolleyarms engage the current-wires2 2 and 3 3 and the carrier travels toward shore.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A marine wharfage system such as described consisting of a trackextending from the shore out over the Water, and at its outer endextending at an angle tothe general line of outward direction, a carrieradapted to travel upon said track, current-wires following the trackalong the major portion of its outward length, insulated guides attachedto the ends of said current-wires, and extending along the track at anangular extension thereof, and a means located upon the shore forreversing the current over the wires.

2. A marine wharfage system consisting of a track extending from theshore out over said track, current-wires following said track, andadapted to supply electric .current to the carrier, a means forgenerating the current consisting of a rotary engine, a rotary generatorconnected at its shaft to the shaft of said engine, a Storage batteryand electrical connections between the generator, battery and currentwires and suitable switches.

In testimony whereof I aflix my signature in presence of twosubscribing'witnesses.
